Just like any graphical application, nm-applet requires a graphical
DISPLAY. So you cannot run it early at boot when you are not yet logged
in a graphical session.

This worked because you already had a graphical session started on
DISPLAY :0.0. You just sent nm-applet to this session.

"export" works in any shell script but is not system-wide; it exports
the given variable only to child processes. There is no "way up"; as
soon as an init script is completed its environment variables die.

nm-applet is meant to be started from within a graphical session (where
DISPLAY is already defined and exported for you). Run nm-applet from
there.
